Have a look at the ulimit flag to increase the 1024 limit (Some other 
application must be hogging the remaining 8).

Oscar's thesis on maximising TCP/IP connectivity (and simultaneously 
open connections) in Erlang based systems might also be of interest. You 
can read it here:

and

Regards,
Francesco
